Embodiment Construction

[0041] The invention provides a method for updating a configuration file and a circuit board, which are used to solve the technical problem of service interruption of a communication device in the process of updating a configuration file in the prior art.

[0042] Usually, designers can use hardware programming languages ​​such as C language, JAVA, C++, etc. to compile and generate configuration files, and load the configuration files into a certain logic device through a downloader or burning chip. When the logic device After loading the configuration file, the function designed by the designer can be realized. For example, the electronic device can load the device driver in the configuration file, and run certain functions in the electronic device through the device driver, such as loading the graphics card driver in the configuration file, then run the graphics card of the electronic device through the graphics card driver. Therefore, configuration files can support the nor...

Abstract

The invention provides a method for updating configuration files and a circuit board. The method comprises following steps: a processor obtains updated configuration files and stores the updated configuration files in the SPI Flash when a first logic device maintains the normal operation of service by using original configuration files; a second logic device is controlled to maintain normal operation of service by using original configuration files; the second logic device is controlled to stop maintaining normal operation of service by using the original configuration files when it is determined that the first logic device has successfully loaded the updated configuration files and maintains the normal operation of service by using the updated configuration files; updated configuration files are loaded from the SPI Flash. By means of this mode, the purpose that service is not interrupted when a circuit board loads updated configuration files is realized; the technical problem that service is interrupted during communication device updating configuration files in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a configuration file updating method and a circuit board. Background technique [0002] The functions of the communication equipment in the prior art are becoming more and more powerful. In order to meet the diverse needs of users, the communication equipment needs to constantly update the configuration files of its own logic devices to meet the increasingly complex services. For example, a rack-mounted switch usually uses a Field Programmable Gate Array (English: Field Programmable Gate Array, FPGA for short) to load a configuration file to implement related logic operations and communication interface functions. This FPGA device has the advantages of high density, low power consumption, high speed, and high reliability. However, the FPGA device is based on the Static Random Access Memory (SRAM) process, that is, the SRAM process, which has the characteristic of losing the ...
